the problem is that if something ion the animation went "outside" the 1024*768 in Edge, then indesign understands that you can go further in iPads dimensions

Exemple: i got a flying object that gets out of the screen, so in my animation at the end it has to be out of the 1024*768 original box right ?

then when i import the html through overlay creator panel in a 1024*768 rectangle it's fine but when i go to the ipad, if my finger moves to the right (where my flying object went), then it does a swipe from the overflow dimensions in some kinf of blank page

I have the same problem here. The edge stage is 1024*768 the browser preview works perfect. But as soon as I import the .oam file to indesign the composition gets stretched and croped. Overflow is hidden.
